## org.mule.util.queue
Class TransactionalQueueManager

    java.lang.Object
      org.mule.util.xa.AbstractResourceManager
          org.mule.util.xa.AbstractXAResourceManager
              org.mule.util.queue.TransactionalQueueManager

All Implemented Interfaces:
  Startable, Stoppable, QueueManager

    public class TransactionalQueueManager

extends AbstractXAResourceManager
implements QueueManager

The Transactional Queue Manager is responsible for creating and Managing transactional Queues. Queues can also be persistent by setting a persistence strategy on the manager. Default straties are provided for Memory, Jounaling, Cache and File.
